Massive sound lag using PsychoPy - Windows WASAPI for external sound card

Builder
2

It appears that the problem is raised because different instances of the device have the same name. Calling the appropriate instance by its ID at least enabled me playing a sound:

sound.setDevice(10, kind='output')

But, I still did not manage to change the WasapiSetting without getting an error.

That’s what I added:

sound.setDevice(dev=10, kind='output')

wasapi_exclusive = sound.backend.sd.WasapiSettings(True)
sound.backend.sd.default.extra_settings= wasapi_exclusive

That’s what I get:
